Recently, the international academic journal Nature published two online results of the fusion of yeast chromosomes, one from the New York University School of Medicine Professor Jeff Burke team, the other from the Chinese Academy of Sciences Center for Molecular Plant Science Excellence Innovation, the Institute of Plant Physiology and Ecology Institute of synthetic biology key laboratory of the research team and its collaborators.
yeast chromosomal fusion is an innovation in synthetic life and another breakthrough for Chinese scientists after the synthetic insulin and transshipment of rnaylate (tRNA) in the 1960s.
results show that humans can systematically and massively modify the number of chromosomes of a species, on the basis of which they can deepen the phenomena and nature of life and uncover the mysteries of a series of major biological problems.
for example, whether the number of chromosomes is related to the function of living things, whether the number of chromosomes is variable, and what advantages multiple chromosomes have for eukaryotic cells over a single chromosome.
the release of the latest research results prove that natural complex life systems can be simplified through artificial intervention, natural life boundaries can be broken by man-made, and even artificial creation of a new nature does not exist in life.
every advance in life sciences will bring great challenges, especially in the field of synthetic life, more attention to the world.
although the results are still a long way from being able to "create" higher life like humans, many people are beginning to worry that it will have an impact on existing social ethics.
more people's fears are more realistic - will synthetic biology be used to make biological weapons? Synthetic biology, like many genomic technologies, produces both beneficial bioengineered microorganisms and potentially harmful to humans and the environment.
as early as 2010, when Venter et al. created Cynthia (a kind of silky mycoplasma artificial life), the United States held a number of field and department hearings, asking Venter et al. to fully explain the meaning and application of both the positive and negative aspects of artificial new life.
hearing sededs on synthetic new life includes 13 aspects such as "what are the risks associated with synthetic organisms" and "what are the prepared protections, controls to prevent the accidental release of artificial life into the environment."
in fact, technology is a double-edged sword, the key to see who's hands.
we should strengthen our awareness in this regard, and when new technologies are emerging, we should look at them carefully and actively respond, and at the same time promote scientific and technological progress, seriously consider the possible consequences of science and technology, formulate relevant laws and regulations, and constantly adjust them dynamically with the development of science and technology, in order to limit their possible adverse effects.
